Morse Micro preps chips for HaLow IoT
Morse Micro Pty Ltd. (Sydney, Australia), a fabless semiconductor startup developing Wi-Fi HaLow chips for the Internet of Things (IoT) market, is now planning to have chips available to ship at the end of 2019.

Wi-Fi HaLow is a wireless networking protocol, written as an extension to the IEEE802.11 standard, that's intended to operate at low power and longer range than Wi-Fi. The IEEE802.11ah extension was announced and published in 2016.

The extension uses the license-free ISM band around 900MHz rather than the 2.4, 5 and 6GHz bands used by conventional Wi-Fi. In theory, the lower power consumption allows HaLow to compete with Bluetooth but with higher data rates and wider coverage. It is thought that HaLow could be a boon to the Internet of Things (IoT) as well as migrating into smart wearables, smart homes, logistics and agricultural IoT.

Morse claims on its website that its chips are capable of 40Mbps data rates, for single-stream, single-antenna products using channel widths varying between 1, 2, 4 and 8MHz, and of up to 80Mbps when using an optional 16MHz channel width. The technology trades off the higher speeds of traditional Wi-Fi for the power efficiency of its protocol and the ability to penetrate buildings and walls.

According to Morse Micro its HaLow transceiver chips will be 5x smaller and lower cost than conventional Wi-Fi chips while providing 10 times the range at 200x lower power.

Morse Micro has said its SoCs provide a "complete solution" incorporating the radio, phy, MAC, security, processor and memory components as well as I/O and connection interfaces and host applications processor options.
